Description

The current allocation policy for ByteBasedBitPackingEncoder is to allocate 64KB * #bits up-front. As similarly observed in ~~PARQUET-580~~, this can lead to significant memory overheads for high-fanout scenarios (many columns and/or open files, in my case using BooleanPlainValuesWriter).

As done in ~~PARQUET-585~~, I'll follow up with a PR that starts with a smaller buffer and works its way up to a max.
